Digital Library of Periodicals of National Academy of Sciences of Ukraine| Резюме: | Complete set of the time-domain modes is presented for a waveguide regular geometrically along its axis Oz . The waveguide under study may have an arbitrary closed singly connected contour L of its cross section. Waveguide surface has the perfect electric conductivity, its volume is filled with a lossy medium with constant electromagnetic parameters ε , μ , σ . Electromagnetic fields of the time-domain modes are products of some functions of the transverse waveguide coordinates, which originate the modal basis, and the modal amplitudes, which are some functions of axial coordinate z , and time t . Modal basis is specified in a general form. Evolution equations for the modal amplitudes are obtained and rearranged to the Klein-Gordon equation, which can be solved easily in compliance with the causality principle. |
